Abstract
Molecular wheels composed of edge‐shared metal‐ligand coordination octahedra usually feature metal ions that are linked by bridging ligands possessing the same type of donor atoms. Herein we describe heterobridged wheels {Run(μ‐SR)n(μ‐X)n}(CO)2n (R=Trip; n=6, X=Cl, Br; n=8, X=I), which were formed in the reactions between Ru3(CO)12, 2,4,6‐triisopropylbenzenethiol (HSTrip) and HX (X=Cl, Br) or I2. These hexa‐ and octanuclear heterobridged wheels featuring thiolate/halide mixed bridging ligands have all been characterized by X‐ray crystallography as well as spectroscopic means including NMR, IR and ESI‐MS.
